Product Description
Sauer-Danfoss MMF Series Fixed Displacement Piston Motors
Product Overview: The Sauer-Danfoss MMF series fixed axial piston motors are high-efficiency execution components specifically engineered for hydrostatic closed-circuit systems. This lineup covers versatile displacements including the compact 25cc (MMF025), 35cc (MMF035), and high-torque 44cc (MMF044). Featured models include the MMF044DASHABNNN, MMF044DAF1ABNNN, and MMF044DAFGABNNN. Renowned for their superior power-to-weight ratio and exceptional continuous speed capabilities, these motors are the premier choice for mini vibratory roller travel systems, paver auxiliary drives, harvester header drives, and auxiliary swing circuits in construction machinery.
Key Technical Advantages:
Optimized Closed-Loop Compatibility: Specifically tuned for seamless integration with M46 variable pumps, ensuring precise power delivery even under extreme reversals and frequent start-stop cycles.
Superior Power Density: The compact housing integrates high-pressure rotating groups, delivering immense torque density while minimizing the physical installation footprint.
High Pressure & Speed Capability: Supports peak pressures up to 350 Bar (5000 PSI) and continuous operational speeds exceeding 4000 RPM, ensuring versatile speed ranges for mobile equipment.
Full Lifecycle Reliability: Constructed with high-strength cast-iron and fatigue-resistant swashplate supports, optimized for longevity in harsh environments characterized by high vibration and heavy loads.
Low Pressure-Drop Design: Internally optimized fluid galleries minimize back-pressure losses and system heat generation within the closed-loop cycle.
